SUBFAMILY II. OEDIPODINJE. 273 



turkey gobbler, oftentimes walks right over it, mistaking it for 

 a wayside pebble. 



Mature specimens of this "Carolina locust," hatched from eggs 

 in spring, have been taken in Vigo County, Ind., as early as June 

 14th and as late as November 22d. It is usually common and mat- 

 ing by July 5th. Either there are two broods each year, or else the 

 eggs hatch at irregular intervals, as freshly moulted individuals 

 have been observed on a number of dates in September, and as 

 late as October 14th. On one occasion, while passing through a 

 wheat field in late September, I observed clinging to the stems of 

 weeds, several specimens of what appeared to be the bodies of 

 grasshoppers with the wings of the common sulphur-yellow butter- 

 fly attached to them. Such a combination aroused my curiosity, 

 but a closer examination proved them to be specimens of this 

 common black- winged locust which had just moulted for the last 

 time, and spread out their soft wings to dry. The inner wings, 

 instead of being black, were light yellow, but in three or four 

 hours thereafter had changed to their usual color. 



This locust is often seen along the walks and in the yards of 

 our larger cities and I have seen specimens about the base of the 

 Soldiers' Monument in the very center of the city of Indianapolis. 

 Both sexes use the wings almost wholly in their travels, and when 

 flushed move in a noiseless, zigzag, seemingly aimless manner for 

 quite a distance, the flight being often more like that of a butter- 

 fly than of a locust. Their hind legs are used only in giving them- 

 selves an upward impetus from the ground and hence are much 

 smaller proportionally than are those of such locusts as leap 

 rather than fly, while their wings are much longer and stronger. 



The Carolina locust is apparently scarce in Florida and con- 

 fined to the northern portion of the State. It has not been taken 

 by me therein, but has been recorded from Jacksonville and En- 

 terprise by Scudder (1877a, SO) and from Marianna by Morse. 

 Specimens are in the Gainesville collection from Lake City, and 

 a pair at hand from Gainesville were taken Sept. 20 by Fattig. 



The distribution of D. Carolina is as wide as that of any 

 other of our locusts, being practically coextensive with America 

 north of Mexico. Scudder gives its range as "U. S. and Canada, 

 ocean to ocean ;" Kirby, as "N. America," and Fox, "All temperate 

 North America from the Atlantic to the Pacific." It is, says 

 Morse (1897, 87) : "Probably the best known of any of the Oedipo- 

 dinse, owing to its conspicuous black wings and habit of frequent- 

 ing roadsides. From the prevailing brown tints of its color it 

 has in some localities received the name of 'Quaker.' In correla-
